ABSTRACT
The paper describes physical foundations of gases generation in different electroinsulating liquids. The authors reviewed literature concerning the analysis of gases generated in these liquids as a result of discharges of low energy. The main purpose of the
research was to compare gases formed in mineral oil, natural ester, and synthetic ester resulting from discharges of high energy,
which has not been studied so far. The comparison was done both in terms of gases composition and their concentration. The
purpose of the research was to give an answer to the question: which of the analysed liquids ensure higher operation safety if there
is a discharge of high energy in the insulating system
